K My invention relates to a separator for light liquids, in which at the inlet or admission place a drosscollector is built in and the flow of water through the separator may be controlled and interrupted by a ioat being subjected to the influence of the separated light liquid. The invention consists therein that the accumulating vessell for the separated light liquid is arranged in the interior of a casing being closed at the top by the mud collector in such 'manner that the water flows over the cover of the accumulating vessel and enters an annular space forming the separating chamber.

vAccordlng to `-the invention the arrangement is such that between the dross collector and the separating chamber a liquid seal is formedby the water flowing into the separating chamber, said seal cutting 0E the separating chamber for the light liquid from the liquid inlet.

A convenient form of the separator is that in which the accumulating vessel for the light liquid forms directly the float, which controls a checking member, over which. the water is carried into the separating'chamber.

In the drawings:

Fig.-1 shows a form of the improved separator in a diagrammatic cross sectional view. Fig. 2 shows a mode of applicationxof the separator, the latter being illustrated in an elevation. Figs. 3 and 4 show a modified form of the separator in cross section and top view respectively.

In the form shown in Fig. l the separator com rises a casing 11, which is closed at the top y a mud collector 2 rovided with an entrance grid 1. In the casing 11 an accumu- -lating vessel 4 for the separated light liquid 40 'being closed by a removable cover 5 is arranged in such manner that the water flows over the cover 5 into an annular space forming the separating chamber. The connection between the accumulatin vessel 4 and the separating chamber is e ected by overflow openin s? provided in the upper edge of the accum ating vessel 4.

The latter is in the present case arranged so as to be a float, which fills up nearly completely the interior of the casing 11 below the grid 1 or on the float 4. If the iloatis empty,

' entl PATENn oFFicE mudcollector, and the cover 5 of such vessel forms a liquid seal 6 for the separating chamber by the water iiowing into the latter, so that the separating-chamber is always gas tightly closed from the water inlet.

The separating .chamber may be shut off from the mud collector by a member 3 controlling the passage Aof water,the seat for such member being formed by the mud collector. Such controlling member, which is ..6 formed in the present case by a valve,.rests loosely on its seat, so that it may be lifted outwards., The valve body is provided' at its upper and lower side with stop stems, by which the valve abuts either on the entrance 6 the valve 3 is maintained in opened position by the lower valve stem. If the float is filled with light liquid, it lowers and releases the valve 3 which closes by its own weight and 70 performs, its closing movement independoi the stroke of the float.' T e light liquid which may be. contained in the water passes together with the latter through the inlet grid 1 and enters the sep- 75 arator, whereas mud and dross for example stones or other solid constituents or the like are deposited on the bottom of the dross collector 2. The liquid passes over the inlet valve 3 and through the liquid seal 6 into the 80 annular separating chamber, whereby on the extended way and by iowing over the large surface of the cover 5 the light liquid is quickly separated. The cover, therefore, acts as a separating wall. The light liquid owing to its reduced specific weight isaccumulated on the surface of the water around the acoumulating vessel 4 and reachingl the openings 7 enters the accumulating vessel 4. The separated water flows below the partition 8 90 in the rising channel 9 and outlet 10 to the drain or the like.

so much of the separated light liquid has been accumulated in the vessel 4 which in empty condition owing to the buoyancy maintains the inlet valve 3 in opened position,\that the buoyancy is overcome, the vessel 4 descends and the inlet valve 3 will close the inlet' by its own Weight. Now, if further liquid iowsA into the separator, the 10G inlet valve being closed, such liquid will no more flow into the separating vessel but darn up at the inlet grid 1, which indicates that the vessel 4 is to be discharged.

For the purpose of accumulating larger amounts of light liquid the separator may be connected to an accumulating receptacle of any capacity, which is connected to the opening 12, such opening being otherwise closed.

If the separator is used as collector for a plurality of inlet channels, as shown in Fig. 2, the casing 11 is situated in a somewhat lower position, so that the upper edge of the same has a corresponding distance from the inlet grid, whereupon between the upper edge of the separator and the inlet grid 1 a pit 13 made of cementor other suitable material is arrangedto which all inlet channels are connected.

In the form shown as an example in Figs. 3 and 4 the mantle of the casing has a square cross section and that of the accumulating vessel a round cross section or vice versa, so that the casing walls contacting the float vessel serve as guides for the latter, whereas the portions of the casing walls being remote from the float vessel enable the discharge device for the light liquid or some other necessary portions to be arranged and secured without hindering the 'loat vessel in Aits movement. The mantle of the casing 1 1 may have a square or other cornered cross section. By such arrangement a perfect utilization and division of the interior of the casing into a light-liquid accumulating chamber and a light-liquid separating chamber is enabled, and in this case the walls of the casing 11 serve at the same time as guides for the oat vessel 4, so that guiding ribs or the like may be completely dispensed with. Moreover by such arrangement will be attained, that the connecting members projecting inwards in the casing, such as the discharge opening 12 and a screen 15 protecting the same do not hinderthe free movement of the float vessel though the interior of the casing is completely utilized.

The mouth opening of the vertical water rising channel 9 at the bottom of the separator may be elongated so as to form a horizon tal .water discharge channel which by preference extends to or beyond the center of the separatingI chamber. By such horizontal portion of the water discharge channel will be prevented that by the water suddenly falling at the side of rising channel in the separating chamber fatty constituents may be carried into the rising channel, since such constituents are separated on the long way tothe mouth, of the horizontal water discharge channel 14. The latter olers a rest to the float vessel being in lowered position.

In the inlet channel 17 of the dross c'ollector 2 a controlling or regulating device 16, for example as shown a slide valve, may

be arranged, by which the separator may be adjusted to the desired amount per second (for example litres per second) of the inflowing liquid.l

The light liquid may be drawn olf either by lifting out or removing the accumulating vessel or bymeans of a pump, for which purpose a socket 18 is fixed in the dross collector, the lower end of such socket passes through the tubular piece 19 of the cover 5 into the accumulating vessel 4 and enables the sucking tube of a pump to be introduced.

In order to prevent the dammed water from getting through the socket 18 in the accumulating vessel a spring urged valve 20 is provided or said socket 18 may be capable of being drawn out or removed.
